An integrated aircraft body

Abstract

The invention discloses an integrated aircraft body. The integrated aircraft body comprises a frame arranged in center, and machine arms symmetrically arranged at the left and right sides of the frame. The machine arms comprise transverse connecting arms transversely extending outside the two sides of the frame, and longitudinal cantilevers fixed at the outer ends of the transverse connecting arms; the front ends of the longitudinal cantilevers are bent and inclined to the front end direction of the frame; the middle parts and the back ends of the longitudinal cantilevers are bent and inclined to the back end direction of the frame; and first mounting holes for mounting a motor are respectively formed in the two ends of the longitudinal cantilevers. The frame, the transverse connecting arms and the longitudinal cantilevers are integrally molded. The two ends of the machine arms are inwards inclined and bent to facilitate to reduce the air resistance in high-speed advancement; and the integrally molded body can prevent the splicing problem in the transmission technology to improve the body reliability.

Description

technical field [0001] The invention relates to the field of aircraft body structure design, in particular to an integrated aircraft body. Background technique [0002] The body of the aircraft is generally composed of a frame and rotors arranged around or on both sides of the frame. Most of the rotors of multi-rotor aircraft extend out of the frame in a straight line, and the design of the cabin on the frame is usually a closed design. The shape of the frame and the wing will bear greater air resistance when moving forward at high speed, which will affect the flight effect of the aircraft. [0003] At the same time, the current multi-rotor aircraft on the market are mainly made of carbon fiber sheets and carbon fiber pipes, which are connected and combined by a large number of fasteners, resulting in the assembly steps of the aircraft body being too complicated to be automated. Ensuring the pass rate of the aircraft, coupled with the excessive connection and combination po...

Problems solved by technology

[0002] The body of the aircraft is generally composed of a frame, rotors located around or on both sides of the frame, and other components. The rotors of most multi-rotor aircraft extend out of the frame in a straight line, and the design of the cabin on the frame is usually a closed design. The shaped frame and wings will withstand greater air resistance when advancing at high speed, which will affect the flight effect of the aircraft

[0003] At the same time, the current multi-rotor aircraft on the market is mainly composed of carbon fiber plates and carbon fiber pipes, which are connected and assembled through a large number of fasteners, which makes the assembly steps of the aircraft body too complicated to carry out automated production. The production capacity is low, and a large number of manual operations cannot be effective. Guaranteeing the qualification rate of the aircraft, coupled with too many connection points of the aircraft body, directly reduces the reliability and service life of the multi-rotor aircraft, and a large number of fasteners bring more weight to the aircraft, which greatly reduces the flight time. reduce
